' To all wwm; #mag/:concern:

Be 'it` known that I, RUDOLPH C.M1LLE1:, .a citizen `of the United States, resid-ing at 'Beaumonh `in the county` of `Jefferson and Statefof Texas, have fin-vented certain new -i and` usefull` Improvementsl -i-n Grain-Doors for Cars,\ofl which thel following is a specif tcation. i f y My Iinvention relatesk to. lnew and` 'useful improvements in doors for grainfca-rs,`

l y The object of thev inventionis to provide va doorthrough whichY grain or ysimilar vcon-` t-entsmaybe readily unloadedfrom a car orV fbinor other container of like character.

WVith the above and otherI objects in viewv my invention has, particular. relation -to cer.

f. Vtain novel Vfeatures of .construction and operation an` example of whichxls given 1n this panyingg;k drawings, wherein y l Figure 1 is a; sideelevation of the door', showing also the adjacent' partsof a freight car. Fig. 2- `is an edge view `of the'idoor showing't-he adjacent partsofthey carin section, takenl on the'y line a-a of Fig. 1. Fig. 3 is. aperspective view ofthe car'door `showing the same open for the discharge of the car contents. Fig. 4 showsa sectlonal view of the door taken on the `lineb-b' of Fig. 3. Fig. 5` is an enlarged sectional view of a port-ion of the door taken on the line c-c of Fig. 1 and showing the shutter andA the folding aprons in closed position.l

Referring now `more particularly to the drawings,y wherein, like numerals of reference designate similar parts in each of the figures, the numeral 5 refers tothe carwall provided withl the usual side opening through which the contents of the car are v loaded. This opening is closed in the usual manner by means of the ordinary slide door 6. In addition to this door I have provided my improved door to be used when the car contains such grains aswheat, oats, etc., or

fruits or vegetables or similar contents.

This door is swung from wit-hin the car in the manner presently to be described. I

Near the top of the car wall and on the inner side thereof I have secured suitable by meansY of bearings 10 which are secured *i to saiddoor andare verticaly slidableoon `safidlrods. lVhen the door `is not in luse it vmaybe elevated on its supportingfralme tand 60 'bodily' folded up to 'the' top of the canand therefsecur'ed by means of hook 11, which "depend's from'the car roof. vand, is disposed A'so as; to readily engage over the bottomend of kthe door when sov folded'. The bottom' j portion ofthis'door kis providedwith a dis- -vlcharge -=0,pening centrally located with `respect to. the sides thereof and provided for 'thefdiscl'iarge of the carA contents `and securedY upon; the `outside of the door and-@on 7.0

each side of the dischargev opening isv an upright cleat 12,l the inner side of; whichfis provided with lengthwise grooves l1321116; 14 v or a purpose hereinafter set forth. specification yand illustrated in1 the-accom- @1s hingedtothe door at .the pointslt, and

which-'when shut closes the discharge open..- `ing of doorg. Theshutter may be secured in its closedI position by means of hooks 71"?,

The numeral 15 refers to-a lshutter which 715` the members 19 and 20. The members are hinged together along the line 21 and the 'members 20 are hinged to` the sid'es of the shutter along the line 22. The free edge of each member 19 carries an outwardiy projecting rib 23 which fits into groove of cleats 12, as shown in Fig. 3,when the shutter is open and secures the aprons to the door.

It is sometimes desirable to shut oft' the discharge of the car contents before the car is entirely unloaded and lfor this purpose I the full length of the cleats 12. The lower portionof each side of this gate is inwardly shouldered, as at 25, so that the lower edge thereofl may fit down between the apron members 19l and firmly secure the ribs 23 in grooves 13, when shutter 15 is open for the discharge of the car contents. Then is desired to cut off the discharge entirely the ribs 19 are removed `om grooves 13 and placed in grooves 14 ci' `cleats 12 as show? in Figyet and the slide gate 24 then entirely closed. 'When it is desired to close slu'itter 15 the gate 24 is elevated and the aprons of the shut-ter are folded rst along line 21 the rib 23 falling between the members 19 and 20 and said members being folded then against said shutter, as shown ,in dotted lines in Figs. l and 5, and the shutter then secured closed, as shown in said Ifigures.

It will be observed that the aprons serve the; double purpose ofsupporting theshutter when the same is'open and the grainis passing thereover, and also form the sides of" a discharge chute of which the shutter itself forms vthe bottom.V Y 1' WV hat I claim is l. A device of 'the character described including a door having a discharge opening therethrough, a closureufor sald open1ng,'

foldable aprons hingedly secured to each side of the closure and detachably secured to said door and so .arranged relative to the closure as to form a chute in combination therewith and a slidable closure .fon-fthe opening carried by the door', said yclosures being arranged to close said discharge open'- ing alternatively, and the last metioned closurey adapted to normally hold the said aprons in an upright position.

2. A. device of the character describedfi'neluding a hingedly mounted support; Y a' door slidably mounted thereon and having a discharge opening therethrough; suitablev Cleats, securedlon said door,rone on eaoh side of'the opening and having two lengthwise grooves on the inner side thereof;'a verti- 'oally sliding closure ,movable in one set of `name to this specification in the said grooves and arranged to `close said opening; a .closure hinged to saidfdoor near its base and also arranged to close said opening, yfolding aprons hinged at one side to said last mentioned closure and havin their other edges free, means' carried by sald free edges disposed so as to engage in said grooves, and' the folding aprons being held normally in position, when the closures are open, bythe said" sliding closure.
